This invention relates to a novel and improved device for treating the human skin and flesh and which, for the sake of convenience, will be termed a vibrator. The novel features ofthe invention will be best understood from the following description and the annexed drawing, in which Ihave shown selected embodiments of the invention, and

in which:

Fig. 1 is a view showing one form of the invention, parts being broken awayV and other parts shown in section.

Fig. 2 is a section on the line 2-2 of Fig. l, but showing certain of the parts appearing in Fig. l in a different position relative Ato each other.

Fig. 3 is a View showing a different embodiment of the invention, in which the motive power is supplied by a different source than in Fig'. l'.

Figs. 4 and 5 are detail views showing the member which contacts with the skin..

Referring first to Figs. l, 2, 4, and 5, I have shown the invention as embodied in a device having a handle l with a removable cover (not. shown) within which is disposed an electric: motor .2, the shaft 3 of which isv connected by any suitable clutch mechanism to a shaft 4 journaled in one end of the handle. Secured to the end of the handle l is a bearing member 5 which has a boss 6 extending through and threaded into an opening in the end of the handle, and in this boss is disposed a bushing 7 within which the shaft 4 rotates. The end of the shaft 4 is provided with a crank disk 8 having a crank pin 9 connected to a piston 10 by means of a connecting rod 11.

The piston 10 works in a cylinder 12 which may conveniently be enclosed within the sleeve 13 integral with the bearing member 5, thus forming a chamber 14 within which work the crank 8 and the connection rod 11. While the cylinder is shown as disposed at right angles to the handle 1, nevertheless it is to be understood that this form is merely exemplary, as other arrangements may be adopted without departing from the scope of the invention.

The end of the cylinder 12 is shown as closed in part by a member 15 adapted to contact with the human skin. This member may be formed of metal or of rubber of varying degrees of hardness or, in fact, of any suitable material. The member 15 is shown as having therein a chamber 16 communicating with the cylinder within which the piston 10 moves, and as being conical in shape, with a small tip provided with an aperture 17. The member 15 is provided with a ilange 18 contacting with the end of the cylinder and may be held in place by means of a collar 19 threaded on to the cylinder and havingl a flange overlapping the flange 1'8.

In operation, the tip with its aperture may be placed against the skin, and the motor may be started as by the operation of any suitable and well-known switch. which, for the sake of sim'- plicity, has been omitted from the drawing.' As

`the motor operates, the shaft 4 will be rotated andv the crank 8 will cause reciprocation of the piston 10 'in the cylinder 12. Since the cylinder is in communication with the chamber 16' and' thus with the aperture 17, it will be seen that a suction will be. created at the aperture 17 as the piston is moved awayv from the aperture. AThis suction action will be repeated each time that the piston thus moves away from the aperture, and as the shaft 4 rotatesrapidly, theresult is a rapid succession of impulses or vibrations in the lair column formed in the chamberv 16, the pulsations causing vvariations in the pressure exerted on the ski'nvat the aperture 17.A Normally, the variations willI be from practically atmospheric pressureA to `a suction and return in sequence, although it is to be understood that itis within the scope of my invention tohave the alternations occur within f or rapid variations in pressure exerted on this part of the skin, which stimulates it and causes the blood to flow therethrough. The skin at the bottom of a wrinkle tends to become set and hard, and the vibrations caused by the rapid a1- ternations of pressure tend to loosen such skin, which also helps to remove the wrinkle. The tip being small and having a small aperture, the action of the device takes place over a small, localized area of skin, which is of value in the removal of wrinkles. I have found it to be of particular value when working on wrinkles under the eyes. The skin acts as a valve to close the aperture 17 and thus to conne the air within the chamber 16.

It will be noted that the piston normally exf tends to a position close to the end of the cylinder, which in turn is close to the aperture 17 in the member 15, which is directly and rigidly connected to the cylinder. This arrangement makes it possible to create a large vacuum, as the space lHlO between the end of the piston and the aperture is small. Whatever the exact theory may be, I have found that excellent results have been obtained in removing wrinkles and in improving the general tone of the skin by the use of my invention.

The minimum suction or pressure exerted may be varied by varying the length of the air column acted upon by the piston 10.4 Such adjustment mayvconveniently be made by the construction shown wherein the cylinder 12 is shown as carried in the sleeve 13 which is split as indicated at 20, the two parts being provided with\ears 21 through which passes a screw 22. When the screw 22 is loosened, the cylinder 12 may be moved in the sleeve, occupying either theposition shown in Fig. 1 or the position shown in Figs. 2 and 3. In fact, a variety of positionsmaybe taken, deA pending upon the length of air column desired.

Again, the member 15 may be removed entirely,' Aand the openend of the cylinder 12 may be placed againstthe skin. When this is done, of course, the skin again forms a valve closing the end of the cylinder, and there are rapidlyrecuring periods when suction is'exerted on the skinby the `action of the piston in the cylinder.

Referring now to Fig. 3, I have shown therein a similar embodiment, and similar lparts are identied by the same numerals. In this embodiment, however, a diierent source of power is employed in the form of a shaft 23 which may be connected to an electric motor or other source of power for causing the rotation continuously. This shaft may be the usual Well-known eXible type,

and may be clutched by any suitable mechanism -to a shaft 24 extending through the handle land corresponding to the shaftof Fig. 1. In other respects, the device in Fig. 3 operates in the same manner as described above. In this gur'e, I have lalso shown the cylinder 12 as being moved Aoutwardly away from the end of the sleeve 13, to

'achieve one of the adjustments referred to above. While I have shown the invention as embodied "in a specific form, it is to be understood that various changes in details may be made without departing from the scope of the invention, and

HI therefore do not intend to limit myself except i by the appended claims.
